I'm feeling numb

I'm feeling cold

I'm feeling like I'm dying all over again
我感覺我又一次在死去
And I don't know why
我不知道為什麼
But I can't get you out of my mind
但我無法將你從我腦海中抹去
I'm going crazy
我快要發瘋了
男聲：
Oh, I'm having a heart attack
喔，我的心跳快要停止了
Oh, I'm having a heart attack
喔，我的心跳快要停止了
Oh, I'm having a heart attack
喔，我的心跳快要停止了
Over you

合唱：
And every breath I take feels like a prayer for you
我每一次呼吸都在為你祈禱
I keep going crazy every time I see you near me
每一次我看到你靠近我，我都會變得發瘋
I can't escape it no matter how much I try to run away
無論我如何嘗試逃跑，我都無法逃脫它
It's a self-inflicted wound and there's no way to save me now
這是一次自傷行為，現在無法挽救我了
I'm feeling hopeless again and it's driving me insane
我又一次感到絕望了，這讓我瘋狂不已
But baby I don't know what else to do but let you in my head and just hope that you feel it too
但寶貝我不知道還能做什麼，只能讓你進入我的腦海，只是希望你也感受到它

合唱：
You're my favorite memory and my biggest nightmare all in one, yeah yeah yeah yeah oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah
你是我最喜歡的回憶，也是我最糟糕的惡夢，喔呵呵呵呵呵呵呵(翻譯) (這句的語氣需要用唱歌的調子表達出困惑、絕望、期待的情緒)
You don't even have to say a word, you got me confused with who and where and why and I can't stop thinking about you (repeat) (這句也帶有很深的感情) 即使你不說一句話，我也可以因你而改變思緒，重複。
